Template name and description in editor too close together in dropdown

[karmatosed]

When you use the dropdown to see the template name and description, both are very close together.

My recommendation would be to just add a single space between them to give some breathing room.

This was seen using the latest version, TT1 blocks and Chrome. I add the theme just in case that's impacting anything here. I will add bug as a label because it makes it very hard to comprehend what is going on without the space.

Thanks for creating this issue. Missing space has been bugging me for a while now, but I always forgot to create PR.

What do you think about the 4px margin-left on the description element?
